Cotton Insect Pest Control with Indoxacarb
Feb 14, 2019
The cotton insect pest spectrum is dominated by the orders Lepidoptera and Homoptera. The status of different pests and control measures on cotton is dynamic and varies with geography and pest complex. Indoxacarb, a new broad-spectrum Lepidoptera control agent with some activity against Homoptera (e.g. Empoasca spp.), has a unique mode of action. Active at low use rates, indoxacarb provides effective control of major lepidopteran pests (Helicoverpa armigera, Spodoptera exigua, S. littoralis, Earias spp. and Pectinophora gossypiella) that attack cotton at all growth stages. Indoxacarb controls pests via stomach and contact activity. Laboratory and field results show consistent efficacy against larval stages of all target Lepidoptera species with additional ovicidal action on some species. Crop protection of 10-14 days is common and the product has a positive temperature correlation. Rapid feeding inhibition and consequent pest death (1-2 days) results in very high levels of crop protection. Indoxacarb is safety to beneficial insects and mites, favouring its inclusion in IPM systems.
